The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Ed and Alan:
There are no analogue TV transmissions from Waltham! They are all digitally encoded these days and formed into multiplexes carrying several channel services. So when you say there were no analogue signals, I'm not at all surprised as they finished more than 5 years ago and in some cases nearly 10 years ago!

Ed: I've had no had channels all day in derby, I've tried a retune but saying no signal. My aerials haven't moved & are all connected ok, I can get normal TV fine but no HD. I'm in the DE73 area of Derbyshire

Poor / no reception started in Leicester LE9 area at 10.15pm on Sunday 5 June and continued this morning, Monday 6 June. An independent aerial specialist came out and advised that he and all other aerial specialists received a message advising of an issue. It cost us 25 in labour charges for a 2 minute test by the aerial specialist who confirmed the problem was not our aerial. Before we booked the specialist we checked online and there were no recorded problems! The specialist confirmed he had been 'inundated' with calls this morning. He also told me that problems with transmitters are almost never recorded on transmitter websites, unlike electricity, gas, flooding, water websites where there is some transparency in service glitches.
Shame that the transmitter people do not feel the need to communicate issues to customers but at least our local aerial specialists are quids in!

S. Harrison : I would have thought that your independent aerial specialist would have been aware that the reason for numerous complaints over the last few days from both Waltham and stations covering other areas is not connected with transmission problems, but a series of high pressure zones sweeping around many parts of the country, high pressure being a condition which allows the reception of transmissions from distant stations of not only within the UK, but also outside of such as Europe.
The problem being, if one of the said transmissions happens to be on the same frequency as one of the multiplexes on the station normally used for reception, this will either result in same being wiped out, or alternatively erratic reception due to the alien signal corrupting the quality of the signal from the local station, evidenced (in some cases) by witnessing pulsed variations in signal quality accompanied by a reasonably high signal level.
Unfortunately nothing can be done to alleviate this type of problem, and which I may say, is one I am sure is going to result in numerous complaints about bad reception over this coming week, as the pressure zones are
forecast to affect most areas in the UK at some point in time, and at times, on more than one occasion.

MikeP: Just to put you into the picture about my sister's errant Philips TV. She tried the no aerial clearout and rescan technique but no change. She called back the aerial installer who repeated everything I did and came to the conclusion that the TV's firmware was out of date with current Freeview standards which is strange but plausible and recommended an external STB. As I said previously my STB which I just happened to have with me performed perfectly and I don't think it has had a firmware update for at least 4 years but something is odd with the Philips TV not doing the usual trick of putting duplicate channels from multiple transmitters in the 800's and putting at least one in the correct location.

There is a difference between 'Poor Quality' due to co-channel interference (which is often a combination of the interfering signal's phase, strength, aerial alignment factors) and the state 'No Signal'. Also the local transmitter's signal propagation range is affected by the ground and atmospheric conditions so weak signal areas loose the signal completely. Most users are able to access their Signal Quality / Reception displays on their Television which differentiate between the 2 signal conditions. Selecting an alternate Channel which is working from the same transmitter site proves the customer's aerial and the rest of your equipment is O.K and it is a reasonable assumption the fault lies with the transmission.
1. Can we not get an article from an engineer / technician who works on the transmitter equipment itself to explain the monitoring of service, how failure status is reported to the control room (SCADA systems etc) and what is the Service Contract demand for repair.
2. Who is in charge of the Transmitter Service fault reporting on this website and who sends in the information during normal work hours and 'out of hours'.......how does this detail get updated on website. What is a better website for this information?
3. Formal contact details stated on website for 'loss of service' reporting on digital channels.
4. How does the lower power levels of the digital transmitters and their frequencies / channels get decided upon and who monitors the impact of atmospheric conditions leading to co - channel interference effects, often from other UK areas using the same channels. Where are these warnings published?

Keith Burrell: Hi, Keith. I can try to answer some of your questions. The majority of broadcast transmitters are run and maintained by Arqiva, which, has strategically placed centres from which engineers go out to attend to transmitter faults, one of these being 'Emley Moor'. Arqiva, as an organisation, seems to have what one might call a 'closed', 'opaque', 'high privacy' philosophy, seemingly unwilling to share information or make it public, perhaps because of terrorist threat worries? I would be surprised if Briantist could persuade an Arqiva transmitter maintenance engineer to explain his work to us, because the engineer would probably be breaking a confidentiality clause in his contract if he did so, and would be summarily dismissed! I think you will find that website owner, Briantist, is responsible for transmitter fault reporting on this website. The information is generally publicly available if you know what you are looking for and where to look, for example, the radio and transmitter investigation service website, run by the BBC, will tell you the transmitter status for all types of broadcast tv and radio, for every postcode in the UK where there is an available service. Other good sources of information are the digital uk website for Freeview tv and ukdigital radio or getdigital radio for digital radio. In answer to your question 3., you'll have to ask Briantist. The power levels and frequencies/channels are determined by international agreements and probably monitored by the UK regulator, Ofcom. Richard, Norwich.

Until a few weeks GO, i WAS ABLE TO RECEIVE, FROM wALTHAM-ON-THE-WOLD
Until aCLIV few weeks ago I ws able to get good reception from Waltham-on-the-Wolds of East Midland news and the BBC News channel in HD, the former from a room aerial and the later from a roof aerial. Within a few days first one, and then the other channel disappeared. Other channels continued to come in well. I tried to do an auto scan to see if I could get the missing channels back, but they did not appear on the scan at all.
Has the power of Waltham diminished, or is anything happening to affect these programmes? I have not changed my equipment in any way.

CLIVE JOHNSON: Waltham is operating with a status of "possible service interruptions" and this might possibly be the reason for your problem, as nothing has changed at said station with regards to transmitter output powers.
However, as your problem involves two transmitters of different powers (PSB1- 50kw /COM7- 10.2 Kw) an assessment of the reception conditions in your area as well as the signal levels expected at same, can only be made with knowledge of your location, preferably being in the form of a post code or one from nearby, e.g: a shop inc post office.
